Heat Sealer Bags and Heat Seal Packaging

Heat sealer bags provide a practical way to pack and protect suitable products. A heat sealer applies heat to compatible packaging materials, creating a secure seal around the contents. Heat seal bags can be used across a range of applications, including food packaging and other commercial packing requirements.

At Kite Packaging, we offer heat sealers for different levels of use, including basic, standard tabletop, industrial, heavy-duty, handheld and continuous models. Our heat sealers can create air and watertight sealed bags, helping to keep suitable contents securely packaged.

Heat sealers can also be used with layflat tubing when creating custom-sized bags. This gives users greater flexibility when packing products of different sizes and allows the packaging to be prepared as required.

How Does a Heat Sealer Work?

A heat sealer uses heat to join compatible packaging materials together, creating a closed seal. The exact sealing process depends on the machine and material being used, so it’s important to check that your chosen bags or film are compatible with the heat sealer.

Different machines can cater to different packing requirements. Tabletop heat sealers provide a practical option for many everyday applications, while handheld models offer greater flexibility. Continuous heat sealers can suit a production line where products need sealing regularly.

Choosing suitable heat seal bags and equipment helps ensure the finished pack is securely closed and ready for its intended application.

Choosing the Right Heat Sealer

The right heat sealer depends on what you’re packing, the materials being used and how frequently sealing takes place. When comparing options, consider:

• Application: Think about the products you need to pack and the type of seal required.
• Packaging: Check that your heat seal bags, film or tubing are compatible with the chosen machine.
• Volume: Consider how frequently products need sealing, particularly for a busy production line.
• Size: Choose equipment suitable for the sizes of bags and products being packed.
• Working environment: Handheld, tabletop and other heat sealers can cater to different packing needs.

Checking individual product information can help users find suitable heat sealing equipment for their application.

Heat Seal Bags for Food Packaging

Suitable heat seal bags can provide a secure way to pack a range of food products. Creating an airtight seal can limit exposure to air and moisture, helping to maintain freshness and protect the contents during storage or handling.

Heat seal bags can be used for suitable baked goods and other foods, including cookies, cakes and sandwiches. This makes them useful across bakeries, catering environments and other businesses preparing food for customers. Sealed bags can also provide a clean, professional presentation for products.

The effect on shelf life depends on the food, packaging and storage conditions. Always ensure the chosen bags are suitable for direct food contact and compatible with your heat sealer before sealing.

Heat Shrink Packaging

Heat shrink packaging uses plastic film that shrinks tightly around a product when heat is applied. Once the item is covered with suitable film, heat can be applied using equipment such as a heat shrink gun or shrink machine.

This type of packaging has several applications. It can help protect products during transit, create neat point-of-sale packaging and secure suitable pallet loads. At Kite Packaging, we offer a range of heat shrink products, including polyolefin and polythene heat shrink film, shrink covers and pallet heat shrink systems.

Choosing suitable film and equipment helps ensure products are securely packed for their intended application.

Vacuum Packaging and Vacuum Sealers

Vacuum packaging works by removing excess air from a pouch before sealing it securely. This can provide a practical solution for hygienic food packaging and can also help reduce the bulk of suitable items.

With a vacuum chamber machine, the product is placed inside a vacuum pouch before the pouch enters the chamber. The machine removes air from the chamber and pouch before creating a heat seal. Air is then returned to the chamber, allowing the sealed pack to be removed.

Standard and industrial vacuum sealers operate differently. The bag remains outside the machine while air is removed and sealing takes place. At Kite Packaging, we offer vacuum chamber machines, vacuum sealers and pouches for different packaging needs.

Heat Sealing, Heat Shrink or Vacuum Packaging?

The right packaging method depends on the products being packed, the level of protection required and your working environment. Each option works differently:

• Heat sealing: A heat sealer closes compatible bags, pouches or tubing using heat. It’s suitable for various applications where products need to be securely sealed.
• Heat shrink: Suitable film shrinks around products when heat is applied. This can protect items in transit, improve presentation or help secure pallet loads.
• Vacuum packaging: Air is removed from a suitable pouch or bag before sealing. This method is commonly used for food packaging and other suitable products.

Consider your products, packing volume and chosen materials before deciding which solution best meets your needs.

Heat Sealer Bags FAQs

Find answers to common questions about heat sealer bags, heat sealing, food packaging and choosing suitable equipment for your needs.

What are heat sealer bags?

Heat sealer bags are packaging bags designed to be closed using compatible heat sealing equipment. A heat sealer creates a secure seal, helping to keep the contents enclosed and protected.

How do heat seal bags work?

Heat seal bags are closed by applying heat to compatible packaging material. The heat creates a seal across the opening of the bag. Always check that your chosen bags are compatible with the heat sealer being used.

Can heat seal bags help keep food fresh?

Suitable heat seal bags can limit exposure to air and moisture once securely sealed. This can help maintain food freshness. Shelf life will depend on the food, packaging, storage conditions and other factors.

What foods can be packed in heat seal bags?

Suitable food-safe heat seal bags can be used for various products, including baked goods, cookies, cakes and sandwiches. Always check that the chosen bags are suitable for direct contact with the food being packed.

What is the difference between a heat sealer and a vacuum sealer?

A heat sealer uses heat to close compatible bags or packaging. A vacuum sealer removes excess air from a suitable bag or pouch before sealing it.

How do I choose the right heat sealer?

Consider the products you pack, the size and type of bags being used, and how frequently sealing takes place. Check the product information to ensure your chosen machine is suitable for your packaging and requirements.
